GEORGE C. JENSEN, OF OAKLAND, CALIFORNIA.

LEVER-Look.

To all whom it may concern Be it known -that I, GEoRon'G. JENsEN, acitizen ofthe United States, residing atOakland,'in the county ofAlameda and State of 1 California, have invented certain new and usefulImprovements in Lever-Locks, of

which the following is a specification.

The present invention relates to an improved construction whereby theshift levers ment of the lever in its operative plane,-.

thereby preventing the operation of the shifter devices by the lever.

With the above mentioned and other ob jects in view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed, illustrated in the accompanying drawings and pointed out inthe claims hereto appended; it being understood that various changes inthe form,,pro-

portion, size and minor details of construction within the scope of theclaims may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is' directed to theaccompanying drawings, wherein- Figure l is a view in vertical sectionof a construction illustrating the preferred embodiment otmy invention.

Fig. Qis a view in top plan view.

ings, wherein like characters of reference designate correspondingparts, 1 indicate the opposing Walls of the member, preferably a gearcase provided with the alined bores 2 closed at their outer ends byplugs or disks 3 pressed or otherwise seated therein. In the bores arereceived the opposite ends of shifter rods or devices l and 5 which liein parallel spaced relation and which are adapted for independentlongitudinal movement when actuated by a suitable lever hereinafterdescribed. I

Bridging the walls 1 and providing a closure for the top of the case isa cover 6 secured in position by the screws 7 which intersect the pathof movement of the shifter rods or devices 4 and 5 and which are pro- Ivided within their length with the reduced portion 8 with which saidrods or devices 4 and 5 operate, whereby the rods prevent the removal ofthe screws from the wall 1 and thereby preclude the removal of the coverfromthe case. The retaining screw 7 at one end of each rod is sopositioned relatively to the end of the rod as to be capable of freeinsertion in position when its cooperating rod is moved to position thegear controlled thereby in power transmitting relation, and the oppositeend of said rod is formed with a recess 9 which permits the seating ofthe screw at that end of the case in positionin its cooperating wall,thus when the rods are in power transmitting position the cover iscapable of being removed from the casing but when in neutral positionthe cover is precluded from removal.

Extending upwardly from the cover is a 1 raised stamping or shell 10,the upper end of which is bent inwardly forming a lever fulcrum socket11, provided at its base with a circular opening 12 through whichextends the lower end 13 of the operating lever 14.

Pressed on or otherwise secured to the leve is a fulcrum cap 15 forreception into the socket 11, the cooperation ofsaid elements providinga fulcrum for the lever which. permits of universal swinging movementthereof.

By reference to Fig. 4 it will be observed that the fulcrum cup andsocket 15 and 11v are oval in plan,'which precludes axial rotation ofthe lever on its fulcrum.

Threaded, as at 16, to the upper outer surface of the shell 10 is alever locking member and retainer cap 17 provided with a sphericalupperend 18 formed with an,

oblongopening 19 therein in a plane parallel with the rods or devices atand 5, in which position operative movement of the lever 14 on itsfulcrum is permitted, the lever being formed at opposite sides in theregion of the wall of said opening 19 with depressions 20 which permitof the lateral or selective movement of the lever to engage one of saidrods or devices 4 and 5; V

On the positioning of the cap 17, as in .Figs. 1, 2 and 3 of thedrawings, the opening 19 is disposed at right angles to the operativemovement of thelever, thus precluding movement of the lever to operatesaid shifter devices 4 and 5. r

Positioned beneath the spherical upper end 18 of the'cap 17 and the'fulcrum cup 15 is coiled spring 21 surrounding the. lower portion 13 ofthe lever and secured at its upper end, as at 22, to the retainer memberand at its lower end passing through an opening 23 in the cup 15 andextending into a slot 24 in the socket 11, said spring rotating the cap17 a one-quarter revolution in a clockwise direction from the positiondisclosed in Figs, 1, 2 and 3 of the drawings.

To preclude movement of the cap 17 from locked to unlocked position, Iprovide the cap with a bore 25 open at its inner end and arranged atright angles to the shell 10, the bore when the cap is positioned as inthe drawings, registering with an opening 26 in the shell 10. 1 Withinthe bore is positioned an inwardly spring'pressed latch 27 provided inits upper surface with a de 7 pression 28 in which extends the offsetmemher 29 carried by a rotatable key controlled locking barrel 30withina casing'31 seated in a depression 32 in an offset 33 formed integral ofthe cap 17. v

On the manual rotation of the cap relatively to the shell and to aposition as in the drawings, the latch 27-is automatically projectedinto the'opening 26, thereby looking the cap from rotation on the shelland precluding operative movement of the lever 14. On .the withdrawal ofthe latch27 from the opening 26 the spring 21 will automatically rotatethe cap on the shell in a clockwise direction until such time as theinner end of the latch 27 contacts with the shouh der-34 formed in theshell 10, and which precludes movement in aclockwise direction ofv thecap on the shell at such time asthe oblong opening 19- is disposed vin aplane parallel with the shifter rods or devices 4; and 5, at which timethe lever 14 is capableof'operative movement. 1

If desirable, a dust retaining shell 35 may viding be secured to thelever to overlie the spherical upper end 18 of the cap 17 to precludedust entering through the oblong opening 19, The spring 21 serves tomaintain the fulcrum cup 15 seated within the socket 11 and also assistsin maintaining the lever in vertical or neutral position.

Having thus described my invention, what i I claim as new and desire toprotect by Letters Patent is 1. In combination with a lever, a tubularsupport through which the lower end there of extends, the upper end ofsaid support providing a fulcrum socket, a fulcrum cup provided with anopening through which the lever extends, said cup being receivablewithin said socket, said cup and socket pro vidin ,a fulcrum for thelever,'a cap attache to the tubular support and provided with an openingthrough which said lever extends and operates, and a spring interposedbetween the undersurface of said cup through which the lever extends,said cup being oval in plan and receivable Within said oval socket, saidcup and socket providing a fulcrum for the lever, a cap having threadedattachment to the tubular support and provided with an opening throughwhich said lever extends and operates, and a spring interposed betweentheundersurface of said cup and said cap for maintaining said fulcrummembers in engaged relation. v
